## Calculating / Multiplying Form Fields (on Exit)?

Jul 16, 2009

This is probably very basic, but I don't think I'm searching the right terms to find what I need, I'm looking for an example code of how to do this.I have 3 columns (form fields below)

PRICE | ITEMS | Total

I want a user to be able to enter in a price and the amount of items so that when they leave one of those two fields, it will autocalculate and populate the "total" field. I also want the option for them to be able to fill out the total field alone, without having to enter "price" or "items". So basically 'total' has to be filled out either way, because I will then be doing calculations with that data.

## Calculating Sum Of Text Fields - N Elements

Nov 30, 2010

They are not very expert in javascript. I created a script that needs to calculate the sum of text fields. My function is limited to 5 elements, you can simplify and make it work for n elements.

PHP Code:
<script>
function somma() {
var a=eval(document.getElementById("primo").value);
var b=eval(document.getElementById("secondo0").value);
var somma0=(a) - ((a) * (b)) / 100;
var somma0=Math.round(somma0 * 100) / 100;
document.getElementById("somma0").value=somma0;�
var b1=eval(document.getElementById("secondo1").value);
var somma1=(a) - ((a) * (b1)) / 100;
var somma1=Math.round(somma1 * 100) / 100;
document.getElementById("somma1").value=somma1;�
var b2=eval(document.getElementById("secondo2").value);
var somma2=(a) - ((a) * (b2)) / 100;
var somma2=Math.round(somma2 * 100) / 100;
document.getElementById("somma2").value=somma2;�
var b3=eval(document.getElementById("secondo3").value);
var somma3=(a) - ((a) * (b3)) / 100;
var somma3=Math.round(somma3 * 100) / 100;
document.getElementById("somma3").value=somma3;�
var b4=eval(document.getElementById("secondo4").value);
var somma4=(a) - ((a) * (b4)) / 100;
var somma4=Math.round(somma4 * 100) / 100;
document.getElementById("somma4").value=somma4;�
}
</script>
<input type="text" id="primo" onKeyUp="somma()" /><br /><br />
<?php for(\$i=0;\$i<=4;\$i++) { ?>
<input type="text" id="secondo<?php echo \$i; ?>" name="secondo" onKeyUp="somma()" value="6" />
<input type="text" id="somma<?php echo \$i; ?>" /><br />

I can't seem to get the math function to calculate and display properly. Can anyone point me in the right direction.

Here is my code.

## "document.getElementById ('total').value = Total;" Not Submitted In Form Post?

Jun 25, 2009

I have a issue with a javascript code that I wrote. This script is a simply for calculating the summation of 2 text input boxes and printing it in another text input box within the form. The entire form is then sent using Form post.The total is written back to the form's total text input box using the code below:

document.getElementById ('total').value = total

This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.

1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.

## Update 'total' Field With Multiple Price Fields?

Nov 11, 2010

i am currently developing a cart for a website at my company.What i am attempting to do is update the grand total field dynamically as the product total (determined by quantity & price) are being populated.Each product in the cart is being generated by a foreach (php) reading from a mysql database.As the total values are not being prepopulated im not exactly sure what the logic would be to get the desired values.

I will also mention im relatively new to the whole web development area, i started begining of this year and feel i could still learn alot about the 'logic' of a computer.If anything is unclear about what i stated above feel free to request additional information.

There are two input fields in a form, but only one of them is required, they are not required at the same time. Either A or B is required. ( A is required OR B is required). In other words, a user can input data to field A, or he can input data to filed B, but he can not input data to Both A and B at the same time. How to implement this constraint in Jquery form validation?

## Calculating Percentage In A Form?

Mar 23, 2010

I am writing a form and doing a bunch of calculations one of which is a percentage based on the value selected. I am returning a correct result for two of the values but for the other two I am not.The 'discount' value is what I am looking for. It should return as 0 for values of 1 but it is doing the math as though it is multiplying by 1. And again for the value of 6 it should be 10% but is taking the value as 4.6 or something.Code is below I've included all of it (sorry) for better ease of understanding the math that is happening:

HTML Code:

<form id="form1" action="" method="get">

## Calculating 2+ Form Field Inputs On The Fly

Mar 6, 2007

I'm working on a financial form that is filled out and then a pdf is outputted (via php).

I'm an xhtml/css and php guy but new to javascript - I'm sure there's got to be a way to do the following with js...

I've got a section for "project costs" with 4 fields (numeric is expected). I'd like to add a 5th field "Total Project Cost" that adds all the inputs of the first 4 fields on the fly as they are typed (or at least, after focus changes).

Also I'd like to have a field which defaults to "10" and a drop down with 3 items that will either add 0, 5 or 10 to the field which defaults to 10.

## Calculating Form - Calculate The Square Footage And Cost Of A Vinyl Banner?

Jul 24, 2010

I'm trying to create a four-box form in which the user enters information into the first two boxes,and the program fills the second two boxes in.Basically,I need a form to calculate the square footage and cost of a vinyl banner.In the first text box the user would enter the banner's height.In the second box the user would enter the banner's width.

The third box would multiply the height by the width and display the total square footage of the banner.So far, I have this part down. The following is what I need help with: the fourth box.The fourth box needs to display the cost of the banner. I have a complicated pricing structure. For example:

If the total square feet for the banner is under 12 square feet, the cost is \$60.00. If the square feet for the banner is between 13 and 25 square feet. The cost is \$4.80/square foot and ect...I believe this would be done using some variation of an IF statement but I can't get it to work.Using this example, what would I add to the form to get this work? The following is the form I have so far which just consists of the calculation of the square feet which is all I've been able to get working.
